All goals came on the power play. Forward Nicklas Jensen, playing the point on the PP, led the attack with two goals.
Goaltender Fredrik Andersen was tested several times, blocking all 21 shots for the shutout.
Denmark now has eight points and sits in fourth place in the group while Norway remains stalled in seventh place with three points, ahead of only Korea.
The Danes are right back at it, playing Korea tomorrow, while Norway has a day off before another tough test in the U.S. on Sunday.
"We’ve put ourselves in a good position right now," Nielsen continued, "but we have another game coming up tomorrow that we have to focus on. I know we’re the favourites, but it’s not going to be easy."
The tense play finally opened after Norway took a late penalty, and Denmark’s power play converted. After some good puck movement, Nicklas Jensen beat Haukeland with a snap shot while Patrick Russell did a masterful job screening the goalie in front.
The Danes almost made in 2-0 early in the second while short-handed. Frans Nielsen made a nice steal of the puck inside his blue line and dashed the length of the ice, only to be stopped by Haukeland on a deke.
Undaunted, Demnark continued to control play and were rewarded with another power play. Jesne scored again on a very similar play, blasting a shot through traffic that found the short side at 6:17, sending the fans into a frenzy.
They scored again with an extra man seven and a half minutes later, this time on a nice pass and re-direct in front, Mikkel Boedker executing the former, and Frederik Storm putting it in to give the home side a commanding 3-0 lead.
Andersen kept the Norwegians off the score sheet with two great saves late in the period. First, he denied Eirik Salsten on a chance from in close, and soon after he made a nice pad save on a Norway power play.
